'10 claims. (0], 12pm This invention. relates. to a'summaryboard whereby a plurality of sheets may be suspended in horizontal overlapping -relationship so that single columns on maybe held in juxtaposed positions to facilitate summarization of the'data contained in the exposed columns.

It is an object each of the suspended sheets of our invention to provide means for removably holding a-plurality 'of banksi'of-sheets overlapped relationship so that data imay be read from the exposed columns of the top bank of sheets along a horizontal line and then the entire top bank of sheets-may be turned-outof the wayto make another bank of sheets available for V computation without the necessity for removing the first bank of sheets from the holdin means. It is a further objectof our invention to provide a line guide ca! pableof hairline adjustment to facilitate reading the data exposed on a horizontal line in the exposed columns of a plurality of separate sheets. .It is a further objects of our invention to provide meansfor holding a plurality of sheets in predetermined overlapped relationship which may be readily removed from its support and parent upon reading the following description taken in conjunction: with the accompanying drawings in which:

the reference. numeral 2 indicatesaflat plate memberfadapted to be sup:-

Y The plate member 2 is providedwith a channel shaped depressed portion 4; (Figure 5 adjacent its upperledge. The;depressed portion may be formed out of thesame blank as the plate member 2, but wepreferto form it,separately and weld it to the plate member .bygmeans of a longitudinal flange 5.1 The, edges 6 and I of the plate member 2'are bent down, to add rigidity to the structure;;.and to cooperate with thebottom edge of the plate.member;2 -and -the. lower edge 8 of the; channel: member 4 -'to f0rm a shallow receptacle forreceiving the easel structure 3 when the sameis collapsed. I 7 A v reinforcing strip 9 welded=to the edge I closes one, endof'thechannel member]. A lug I 0 is secured to the reinforcing strip 9 in any'suitable manner and projects over-the channel. The other .end of the channel is ,closedby a slide member I l which ,:is;secured to'thebottom of the channel memberrlfifbygmeansof a pair of studs l2, l3 projectingthroughaslot: Min the member H. The free end of the slide member I I is bent over, as; indicated at JBgFigure 5, at the same; height as'the lug '10. ,qThe slide member l l is provided with afinger piece, I6 toqfacilitate its manipulation.x g

The channel shaped depressed, portion 4 is adapted to receive a;ring bar 11. The ends of the ringqba'r H are open: so that it may receive .of thertoggle plates with its edges embracing the edgesofxthe member 20. to give the top of the ring bar'a finished appearance. A reinforcing member 26 is secured to the ring bar I! by means of a plurality of {integral tongues 21 projecting throughfslots 28 in the metal plate :20. The reinforcing member 26 is provided with a pair of depending flanges 29, 30, so that the ring bar v mayiliefiat onua desk or table. The flanges 29, f

x Cl 33 also add rigidity to the reinforcing member 26.

The ring bar I1 is adapted to receive a plurality of banks of loose sheets 3|. Thesheets 3| are punched at their top edge to form a plurality of apertures 32 so that the sheets may be arranged in horizontal overlapping position with a single column exposed on all .the sheets except the first. The data to be'summarized is contained within the exposed columns. The various banks of sheets may be separated. by means of index sheets 33 provided with index tabs 34 and punched that the, number of sheets that can be summarized to fit on the ring sections 2 I 22.

A pair of flat strips 35, 35 extend from one edge of the plate member-{adjacent the top and,

bottom, respectively. Thestrips 35, 35 may be integral with the plate 2 or may be'secured to the plate in any suitable manner. The strips 35,

36 are provided with apertures ii-throughwhich bolts 38 extend. The bolts 38 are threadedinto opposite ends of a rod 39. A portion of these:

tudinal edges of the line guide are beveled, as

indicated at '43, 44, to facilitate "reading of data along a horizontal line from the exposed-columns of the sheets3|.- The top and bottom walls of the housing 4| are provided with apertures 45 through which the rod 3S'ma'ypass. l A pair of rollers 45;41 are-mounted in the housing 4| on one side of the rod 39' byineans of studs 48, v -The rollers 46, 41 are each provided with adepressed center portion and conical bearing' portions 5|, 52 (Figur'e '7). A metal 1 plate "53,- U-shaped in crowsection, is mounted inthe housing on the side of the-rod 39 opposite from the rollers, '41. A pair of studs 54,55 project from the rear face-of the center portion of the plate 53. Coil springs 56, 51 surround the studs 54,55 and force the plate 53 towards the rod 33. The center portionof the plate 53 is provided withtwo apertures 58, 53. A roller 60, mounted-ion a stud 5| securedto the legs of the metal plate 53, projects through the aperture 58 so that its periphery contacts with the'rod39. I

Another'roller 62 projects through both legs of the plate 53, the front wall of the housing 4| and the fixed end of the line guide 42. The roller 62 is serrated as indicated at 64, Figure ,8, so as to interen'gage with the serrations 40 on'the rod33. A knob55, preferably having a roughened edge, is secured to the pin 63 by means of a set screw 36. V The operation of our summary board is a followsra T A plurality of banks of sheets 3|, separated by the index sheets 33, are positioned in overlapping relationship on the ringbar H. The lineguide is pushed approximately to the horizontal line containing the data to be summarized. The knob 55 is then turned to position the line guide accurately. The interengaging serrations 40 and 64 enable the positioning of the line guide with hairline precision. When the operator is finished with the data on one bank of sheets the line guide is turned out of the way and the index sheet, with thebank of sheets on. top of. it, is turned over the top of the summary board. f The next bank of sheets is then available for any desired computations and the line guide may then be turned back to indicatethe same horizontal line onthe newbank of sheets. Inthisway it is possible to is mounted on a pin "which summarize data on a single horizontal line from several banks of sheets without bothering with sub-totals and without the necessity of positioning the line guide for each bank of sheets.

If it is desired to reverse the sheets, the slide member II is pulled outwardly by means of the finger piece l6 and the ring bar I! isslid off the lug ID. The ringbar is then reversed and the slide member is then moved back to holding position. A pluraltiy of ring bars I! may be used inconnection with a single summary board so without removing the sheets from the ring bar is not'lirnited by the capacity of the ring bar. The use of a plurality of ring bars with one summary 'board'is advantageous also because the ofiice boy can be filling up one ring bar while the clerk'is computing data from sheets mounted in another ring bar.

While we have described a preferred embodiment of our invention in detail, it will be understood that the description thereof is illustrative rather than restrictive, as many details may be modified orrchanged without departing from the spirit or scope of' ourinvention. Accordingly, we do not desire. to beirestricted to the exact construction described except as limited by the appended claims.v I r f 1 We claim: f 1; In a summary board, a ring bar including a plurality of ring sections mounted on a pair of toggle plates, a pair of curved metal plates enclosing said toggle plates, and'a metal reinforcing member. secured to thelowermost .curved metal plate, said reinforcing member being "provided with a 'pair-otdependin'g flanges.
